This invention relates to a machine to trim the excess or waste allowance from, embroidered' work in the nature of scalloping. This is a; continuation-impart of application Serial No. 82,266', l'ed'li/larch 1Si 1949, now abandoned'.

A large part` ofthe embroidering trades devotes itself' to applying scallopin'g to base materials. This' 'consists of' sewing ornamentalv threads, frequently over a llerfcord or thread, to a fabric or a portion of a garment, such as a skirtcr a collar, in a pattern made up ofa seriesA ofl arcs joined' together to formv anV undulatingdesign. The excessy or waste materialY trimmedr from the edge of the scallop, usually byhand. As these convolutions may be very intricate, cutting away the waste requiresV great skill and adeptness, andA considerable patiencewvith atediu ous job. Necessarily, the rate oi production is low, and' the cost is'thereforeY high; as damageV can readily result if 'care is not diligently exercised.

' A number of attempts have' been made to develop mechanicalA means to a'ccomplish'fwliatthe .skilled manipulation of the hand'y trimmer does. Some are in use, butstill-require considerables'kili on the parteithe machine operator;v Such machines are effective'only when rcutting Waste from long strip vbase materials, cut on'wha-tisknown as the straightPl-as, if anyof the Work, such as a collar; is ell-tion the 1bias, it cannot bey handled successfully.' y

This new machine therefore has as its mainobject to provide a reliable means'o' trimm-ing this excess ore-waste material from scalloped emi- Vfeed mechanisms and to so position ther-nv with respectl to the -cuttin-gmeans that effective controlfisretained of thefwork' regardless Whether thebase materialis cut ony theV straight or bias` l 1 I (cl To provide Inevel means of regulating the amount ci? feed er each of the co-operating feed mechanismsso that therequirementsofany par-- ticiiflar-base material may be readily met ingpresser shoes so that the requirement of [any particular base fabric may be meti. and readily reproduced, as required'.

Fig. 10 is a section taken on line lil-ID of Fig. 3 showing the relationship of the eccentrics, the slide blocks and the feed bar of one feed mechanism.

Referring to the drawings, and Fig. 3 initially, it will be seen that the machine comprises main bed casting It having top surface Il and two arms iii and I3 bored to receive bearings in which mainshaft i@ is furnished. Right and left feeder mechanisms mount respectively on inner vertical faces le and i5.

Mainshaft I5 is provided with three bevel gears for power takeoff. Bevel gear set l1 operates the right feeder mechanism; bevel gear set i8 operates the left feeder mechanism, and bevel gear set iii operates the rotary shear member 25. Thrust washers 20 are used where required.

Mounted on surface il when the machine is assembled, as best shownin Fig. 1, is a work supporting plate 2i, attached to bed Hl by means of screws 22. A rectangular opening is provided centrally in plate 2l to receive in flush relationship therewith, a hardened steel throat plate 23, held therein by means of screws 24. Operating through throat plate 23, are a cutting means, and two separate feeder means. The cutting means which is the subject matter claimed in a companion continuation-in-part case S. N, 336,919 filed February 16, 1953 will first be described.

A rotary shear member 25 is mounted for rotation on its shaft 2t in a bore in bed lil. Although not shown, shaft 2S rotates in ball bearings for obvious reasons. Shaft 26 is driven by means of one of the bevel gears sets i9 at a suitable speed which may be selected by using appropriate ratios for such gears.

Shaft 2E is mounted at an oblique angle to pitch the multiple toothed shearing face 21 of rotary shear member 25 at an angle which facilitates cci-operation with the embroidery senser and deiiector 93, for the co-.action which will be subsequently described. The hub portion 28 of shaft 2t serves as a spacer for the proper positioning of shear face 27 with respect to the other co-operating parts.

As best shown in Figs. 6 and 7, rotary shear member 25 is provided with a large number of peripheral shearing edges 29 on face 21, and with a suitable back clearance, as by a bevel 301.

Co-operating with rotary shear member 25 is a ledger blade 33. As best shown in Figs. 4 and 5, a ledger blade mounting lever 3l is provided with a top fiat surface 32, in which a ledger blade 33 may be inset as by brazing, in which case a long wearing material such as tungsten carbide may be utilized as the stationary shearing edge 34. Lever 3i is pivotally mounted by a pin 35 retained in the 4 arms 38 of a yoked support 31, which is suitably held by its shaft portion in a bore in bed I0, as by a set screw 38.

Shear edge 34 is resliently urged against shear face 21 by means of a spring 39 bearing against the lower end 463 of ledger blade mounting lever 3 l. Spring 39 is retained in a socket in support 31.

The pivotal mounting of lever 3l is so arranged that the shear edge 34 overhangs the pivot pin 3E, so that the downward drag exerted on the work by the rotation of rotary shear face 2'! will always tend to bring the shear edges into closer engagement, making not only for more eficient shearing action, but also preventing the material from coming between and separating the shear edges and rendering them ineective.

Referring to Fig. 6, it will be seen that the multiple rotary shear edges 29 are inclined at such an angle, that as face 21 rotates (in this instance downwardly), there will be sequential and progressive engagement of each shear edge 23 with the stationary shear edge 34, which is highly desirable.

Ledger blade mounting lever 3| has been shaped to permit necessary clearance for the other operating parts of the machine as shown, but it need not necessarily be of this particular shape, nor need it be mounted as shown. For example, if rotary shear member 2E were to rotate upwardly, it would be entirely feasible to apply the stationary shear edge to the embroidery senser and deector Sil at S8, in which case, the opposite shear edges on shear face 21 would be utilized.

From what has been described so far, it will be readily apparent that any work which is passed over plate 2l to and over the throat plate 23 to the cci-operating shear edges 29 and 3d, will be severed by the shearing action thereof, as power is applied to the machine. To better support this worlr for this severing action, and to prevent any part of it from being drawn downwardly by the rotation of shear face 2, top surface 32 of ledger blade mounting lever 3l lies substantially flush with throat plate 23, and partially surrounds the rotary shear face 21, with suitable clearance at the nose portion lll thereof to prevent interference with the shear edges 29.

As will be noted in Fig. '1, however, throat plate 23 does not abut the back of shear face 21, but instead, there is considerable clearance, which it is found permits any waste which might become wedged between the edge of throat plate 23 and the back of shear face 2l', to be pulled out by the action of the left hand feed mechanism.

rlhe means for automatically advancing the work to the severing means consists generally of two independent feeder mechanisms whose coaction may be varied so as to provide suitable feed motions to transport the work to the severing means in a manner which will effectively sever the waste or excess material from the edge of the embroidery, but will not result in injury to the latter.

As seen in Figs. 2 and 3, there is a right mechanism and a left mechanism. As both are similar in structure and action, only the right feeder mechanism will be described as illustrative of both, it being understood that suitable reversal of the parts will be necessary to obtain the left feeder action. Corresponding parts of each mechanism bear related numbers, the left mechanism parts being numbered 133 higher than those of the right.

As best shown in Fig. 3, it will be noted that .accuses each mechanism. is driven. from mainshaft. t6 by means oi bevel gear sets I-T-and I8A respectively.

Two drive shafts 45 and I45-arejournalled in bedlif, and inclined at a suitable angle to each other. The operating portions of such shafts extend re-v spectively through faces |14 and I5f-of bed l0.

Referring nowv only to. the right feeder mechanism., drive shaft 5 is provided withtv/o eccentries 46 and lil which provide the desired four motionaction of the yfeed dog 53, through alinkage which will now bedescribed.

This four motion action is made up oi a lift or vertical component andl a feed or horizontal component, suitably combined to advance the. work intermittently from the cutting members after the severing action. The lift. component. is;` derived from the rotationof` eccentricy Iain lift bary 50. To minimize the Wear that would result trom such rotation or the eccentricv 4S in the slottedportion of bar' 5d, eccentric 46 rotates in a flanged slide block 48, through which the lift oscillating motion of lift bar 5c is eiiectively derived'. Lift bar 5%) is milled at 52 so that feed dog 53 mavbe mounted thereon, as. by a screw 54; Lift bar 5c is pivotally mounted cn a rocking yoke 55 by means of pin. 5G.

It will be seen that the feed-dog 5.3'. will be alternately lifted. and lowered on an arcuate pathy about pivot pin 55. If pivot pin e6' were to osei'llate in an arcuate-path. about. pin '51. which mounts rocking yoke 55 on face it. civ bed lil, then the resultante o1"- such arcuate 'motions in properly timed relationship would bring about the-desired four motion feed action. It would also. ifo-llow that if the extent of rocking of yoke 5,5; were varied, then the length of feed stroke of feed. clog 53. would also vary.

The means for rocking yoke 5.5 and for select'- ing the amount of such rocking Will now be described'. Eccentric A1 rotates in slide block 49. in a slot in feed bar 5i., which is also pivotally mounted on pin 56 in yokev 55. Feed bar 5i. has` an extension arm 58 which carries a pin 5S, on which a link 5t is pivotally mounted. The other end ci link 60 connects by means of pivotpin 6I with. a segment gear. lever 82, which is pivotally mounted on iace lli. by means of pin 53'. Lever E2 mates with worm 64, mounted in ears 65.011 ace le, on a Wormshaft S5, having a slotted.

end 6.1. y

For anyk given'position'of' lever 62, which it is. apparent is. adjusted. by turning worm 64 byA means of a screwdriver.v in the slottedend f-'Lpivot pin Si. will beheld in a locked position on an arc aboutpin 63. YFor any vsuch locked position, link 6.0 will be cscillatable about. pinSl.V Hovv-4 ever, lthe point aboutwhi'ch link 6.0. canrock will'. depend upon any adjustment of the Wcrm64;

Since link @t and karm 58L are .connected .by pivot pin 5t, as oscillating motion is applied'byf eccentric 131 to the slotted end oi feed bar 5l, the resultant will be. an oscillation ofi 11i-n.56 as: yoke. 55 rocks. in the arcuate path4 about pin 51 mentioned previously.' The. amplitude of. this; rocking ci pin 55 about, pin 51; ywill depend upon the. position ci pin 6i on the arc. about-pin 6:3 `on which it may be vadjusted by setting: of the worm 54. y Y' Hence aslever Zis adjusted from .one eXtrem-e. tosthe other, vand. the positionoi pin tl. is varie v thereby.. the amplitude of rocking.. ofpin .d6 will befvariedresnlting in a variation from'. a maxi.- muxn .feed stroke. to. a. minimumizeed stroke- Zaand 3;, .thepositions of1adjusinnentv oleverscz; andtzfhave been shown soi-.tbatithe GOL right. hand feed mechanism is. set. for maximum ieedfstroke, while the left hand reed' mechanism isrset for minimum feed stroke. Obviousl', any desired stroke between these`v limits may be selected for either feed. mechanism by appropriate; turning of wormshafts. 65; and 1.65. For this purpose platezzlf has openings on either side thereof (see 1f) through which a screwdriver may be:y inserted to engage the slotted` ends El and itil. for such; adjustment. Suitable. legends. appear about.' such openings to indicate in which direction the respectivevvorrn. is to be turned to ob.- tain. the desired feed stroke.

The feed: strokev of yeach feed mechanism is U therefore independent, and readily adjustable ily and independently adjustable to meet the requirements of any particular base material.

rig-ht. and left presser foot. assemblies are bestehen/n in. "ig, 2. Presser feet support bracket O is vertically mounted in a bore in bed lil. Bracket 1i). has. a right arm H and a left arm lll.

Inv thelower surface of right shoe di, a groove 82 may be providedto. allow the embroidery to pass, therethrough. The. purposev of this; is to prevent loss of control over Vthat portion of the base material about. rthe embroidery which must be fedawaythe cuttingmeans after the waste has been severed. Itis evident u suchgroove SZ: were notk provided, the raised crnbroidery. could lift. shoe tl, thus. losing covnoleteI engagement ci; the teeth of the feed dog E3 witi thefwork, andy control of the right feed moveu ment. Y

As it is desirable to raise the .presser sho-es for the. f insertion ci.. their respective Afabric portions between .themanc' thefco.- operating. feed dogs; sol

that such sections may be respectively transported following their severance, means have been provided in each of the arms 1| and |1| to permit the presser bars 13 and |13 to be raised in the conventional manner.

A lift pin 83 attached to right presser bar 13, extends through a vertical slot 84 in arm 1| to be engaged by a presser bar lifter 85, which is pivotally mounted on a shouldered screw 86 threaded into arm 1 A stop pin 81 is provided to hold lifter 85 in its idle position, above the level of the work. It will be seen that as the end of lifter 85 is raised, the cam surface S0 thereof will raise pin 83, and hence bar 13, against the compression of spring 15. As a part of this cam surface 88 is suitably shaped to provide a locking position, it will be seen that lifter bar 13 may be retained in raised position thereby, as desired.

The action of the presser feet in conjunction with the feed dogs is well known. The combined feeding actions will be subsequently described in conjunction with the action of the cutting means, and of the embroidery sensing and defleeting means which remains to be described.

An embroidery senser or feeler and deflector 90 is adjustably mounted on an eccentric portion 9| of a shaft 92 which is obliquely mounted and which may be turned in a bore in bed I0. Deflector 90 has a hub portion 93 in which eccentric shaft portion @i is received and held in adjusted position, as by a set screw 94.

The adjustment of the deflector 90 off center of shaft S2 is made by loosening set screw 94 and turning' knurled head |03 of Wormshaft |02 in the required direction and then retightening set screw 94 in the adjusted position. This per mits deilector l to be positioned forwardly or rearwardly of shear edges 20 as required to provide suitable clearance in the recess 96 in the back face of deector' 'J0 for the shear face 21. When rotary shear member 25 is resharpened, its diameter will be reduced, and the adjustment mentioned will permit optimum positioning.

The nose section 91 of deector 90 is shaped, as best shown in Figs. '1 and 8, to assist in defiecting the embroidery from the cutting means, but to allow the waste to be cut away as shown in Fig. 8. it is desirable to trim as closely to the edge of the embroidery as possible, Without actually cutting the latter. 1For this purpose, deflector 9d has been 'thinned at 98 to permit the scallop edge to come right up to the shear face 21, but to be separated therefrom sufciently to prevent damage. The oblique mounting of rotary shear member 25 previously mentioned, actually permits the shear edges 20 to project slightly under the applied embroidery S as the Work is severed. The deector Q thus has no apparent thickness at although the vertical wall thereof will be in contact with the raised embroidery to keep it from being cut by the rotary shear member 25. Thus the waste is out away right up to the edge of the scallop.

Contributing to this arrangement is the fact that deflector 90 rests above ledger blade 33 with just suiicient clearance to form a throat through which only` the base material may pass. It is desirable to maire this throat adjustable, rst to accommodate different thicknesses of different base materials, and secondly to permit the throat to be opened for the insertion of the work.

This is accomplished by means of a worm gear it@ fixed on the lower end of shaft 92, which is engaged by worm |0l, mounted on a shaft |02,

one end of which extends through plate 2|, and has a knurled head |03 for adjustment of the deflector 90. To permit accurate resetting of the throat opening for any given base material, a calibration means is provided, consisting of an indicating pointer |04 mounted on a shaft 505 carrying a large spur gear lll. A small spur gear |01 on shaft |02 will cause the pointer me to be rotated adjacent a suitable scale on the surface of plate 2|, when the knurled head 93 is adjusted. Hence for any given adjustment there will be a `given scale indication which may readily be reproduced. The choice of the gears i 06 and |01 has been dictated in this instance by a desire to amplify the readings for fine adjustment. Obviously, a choice of any suitable ratio will provide the degree of amplification desired.

Of course the means to adjust the throat opening and of Calibrating it as shown and described herein are merely illustrative, as there are many other means available for accomplishing the saine result.

Having described the structure of the various co-operating parts of the machine, their co-action in operation to perform the desired separation will now be explained.

Referring to Fig. 8, it will be seen that the work consists of a series of scallops embroidered on a base material. When power is applied to the pulley, the rotary shear member 25 will begin to turn, and the right and left feeders will begin to feed rearwardly, The waste portion and the scalloped portion may be initially separated as shown in Fig. 8 by hand using scissors, or the operator may feed the work to the cutting means until sufficient separation has been obtained to permit the waste portion to be placed beneath the left presser shoe, and the scalloped portion under the right presser Shoe. To permit this initial cutting, the deflector 90 may have to be raised by manipulation of the knurled head it so that the throat clearance is wide enough for this purpose. The throat opening is adjusted so that only the base material may pass therethrough.

Lifter is then .raised so that the waste portion may be inserted between the left shoe and feed clog, and lowered, making the left feed effective. Lifter 05 is then raised and the em broidered portion inserted between the right shoe and feed dog, the scallops being centered in the groove 82 as shown in Fig. 8. Lifter iti is lowm ered and the right feed then becomes effective.

The tensions on each presser shoe are then respectively adjusted so that the Werl; portions may be fed rearwardly, but so that enough slippage between the shoes and feed dogs will be permitted so that each feed may become momentarily less effective if the respective work portions are retarded.

Both feed means will now begin to advance the respective portions of the work piece rearwardly, the right feed'drawing the embroidered portion oi to the right, and the left feed drawing the waste portion off to the left.

Assuming that the edge of any of the scallops is now spaced to the right of the defiector 9S, the left feed will draw the work piece to the left until some portion of the nose el of deflector e@ comes in contact withy the raised embroidery, at which time the movement to the left will be momentarily halted, the left feed having become momentarily ineffective because the raised embroidery cannot pass through the throat opening.

The right feed means will still be effective, and

V,the scallop to the .shearing means.

9 will continue to 4draw the work .rearwardly and to the right. As soon as this results in the scallop being spaced from the deflector S, the left feed will again become effective, `and draw the work over vagain until it comes into contact with the deflector. K

This combination of feed movements will ultimately result in the entire undulation of the scallops coming into contact with some portion of the nose 3l as the wor-k piece travels rearwardly to the right. To accomplish this, the respective feed strokes .of the right and left feeders, andtheir timing may have to be adjusted to obtain a proper balance of these respective motions to bring about the desired result, when the machine will become self feeding.

The effect of this resultant of feed movements on the work piece will be to present the edge of The rotary shear member makes .a multitude of short scissors-like cuts in the base material adjacent the edge of the embroidery, as the latter is supported bythe stationary shear member. As deector 9B is of reduced cross section at S8, which isin the immediate vicinity of the cutting action, and as the cutting .action actually extends under the defiector at this point due to the pitch of .the rotary shear face 2l, the result will be a series of cuts infsuch close proximity to the edge of the embroidery that no objectionable margin will be left.

Nose vpiece Sl has been .shaped to permit the corners of the scallops shown in Fig. 8 to be effectively trimmed. If other shapes of scallops having very sharp corners are to be trimmed, it is understood that the nose portion Sl may be adapted accordingly.

The yparticular cutter means shown and described is desirable because it makes a multitude of short scissors-like cuts, which is vvery effective for the purpose. However, other cutter means could be readily substituted as long as relatively shortcutting action results so that the undulations may he properly trimmed as the deiiector senses the intricate configuration of the embroidery.

The positioningof the respective feed means in the immediate vicinity of the cutting action, as shown and described results in complete control fthe Work., regardless whether the base material is-cut on the straight or on .the bias This overcomes the disadvantages of previous efforts to solve this problem. Such positioning enables the machine to be used to trim collars and cuffs, which is beyond the capabilities of previous machines.

The invention therefore .provides a versatile machine capable of operating on a wide variety of embroidery work with .great rapidity and accuracy.

While the presntly preferred embodiment of the invention has been described in detail for the purpose of illustration, it is to be understood that the invention is not limited to the details of the vconstruction shown and described, but it is to be .construed broadly within the purview of the claims.
